Title: Improvements relating to the hydrocatalytic desulphurisation of hydrocarbons
IPC: C10G45/02
Filed: 1954-04-15
Abstract: Hydrocarbons are hydrocatalytically desulphurized by contacting them at a space velocity within the range of 0.5 to 10.0 v/v/hr. of the liquid feedstock and in the presence of 1,000-10,000 SCF/B of hydrogen, with a catalyst consisting essentially of the oxides of cobalt and molybdenum on a support consisting essentially of alumina, the catalyst containing a small proportion of fluorine, at a temperature of 650-850 DEG F. and a pressure of 200-1000 p.s.i. gauge so that the organically combined sulphur contained in the hydrocarbon is converted into hydrogen sulphide, and then separating the hydrogen sulphide.  The catalyst is preferably that described in Specification 719,627.  In an example, a Kuwait gas oil of 248-359 DEG C. boiling range containing 1-26 per cent of sulphur was treated at 780 DEG C. and a pressure of 600 p.s.i.ga. at a space velocity of 4.0 v/v/hr. and 4,000 SCF-B gas recycle to give a product containing only 0.03-0.04 per cent of sulphur.

Title: Method and ''paratus for the manufacture of sintered products
IPC: C04B7/36
Filed: 1974-03-14
Abstract: 1463393 Cement manufacture ZEMENTANLAGENBAU DESSAU VEB 14 March 1974 [31 May 1973] 11466/74 Heading C1H [Also in Division F4] In making a sintered product (such as cement clinker) a liquid fuel is absorbed in a part of the raw material to be sintered. As shown, raw material from a bin 11 and liquid fuel from a preheater 10 are mixed and granulated or pelleted at 12. The granules are fed through a preheating stage 3 to a combustion chamber 2 above a fluidized sintering bed 1. Combustion air 15 passes upwardly through the bed 1. In the combustion chamber 2, the liquid fuel in the granules vaporizes and is ignited. The granules burst to form particles. An eddying zone is formed above the bed 1. Raw material to be sintered is also supplied to the apparatus through feed pipes 14. As this material passes towards the bed 1, it is preheated by upwardly flowing hot gases. This preheated material, when it reaches the eddying zone, agglomerates with the particles therein. The agglomerated particles then drop on to the fluidized sintering bed 1 where their thermal treatment is completed. This forms a layer of sintered particles which due to their weight are at rest. These sintered particles are discharged through a shaft cooler 17 where the incoming combustion air 15 is heated. In a modification, a binder or a solid fuel is added to the mixture of raw material and liquid fuel.

IPC: G01N3/06
Filed: 1931-04-17
Abstract: 369,432. Testing sicalphy qualities of materials. HOUNSFIELD, L. H., 3, Durrington Park Road, Wimbledon, London. April 17, 1931, No. 11481. [Class 106 (ii).] In a machine for testing yield point, tensile, compression, and bending stresses, breaking strength and hardness having a stiff spring through which the load is applied is provided with optical means for measuring the deflection of the spring. The ends 9, 10 of the specimen are connected to grips one of which is connected to a lever 14 fulcrumed on a pin 15 on a link 16, the other grip being connected to a disc 7 connected by bolts 8 to a similar disc 6. The latter engages centrally a stiff spring 1 supported at the ends by cylindrical knife edges 2 resting in rigid buttresses 3 on the base casting 4. The disc 6 is centralized by thin plates 26 riveted to the disc and clamped between rubber buffers 5 and the ends of the spring. A vertical strip 27 riveted to the disc ensures central application of the load. The grips are in two halves the lower one 30 of which is attached to the spherical head 11 by a thin pin 31 so that the specimen may be readily laid in the lower halves 30 and then the upper halves 32 applied and secured by retaining rings 33. A microscope 71 is mounted on a slide 75 and a single line on the spring 1 may be observed but preferably a spring clip 72 holding the abutment end of a needle 73 is provided. A graduated graticule in the microscope enables the movement of the spring to be seen on a large scale. The microscope is adjusted so that the pointer end is at zero before the load is applied. By varying the distance between object glass and eye-piece the graticule may be adjusted to suit a particular spring in use. It may then read in. tons per square inch. The effective length of the spring may be varied for calibration purposes or a cross-wire in the eyepiece only may be provided. The instrument may be moved in its slide by a micrometer screw. The load is applied by turning the screw 13 by means of the handle 12. For bending tests one chuck carries two spaced knife edges and the other a central knife edge engaging on opposite sides of the specimen which is arranged transversely to the ordinary positions for tension test. For Brinell hardness tests the back of the disc 6 carries a ball 61, and after the specimen has been placed against the ball a screw 63 is moved up to it and clamped whereupon a load is applied by turning the screw 66 to advance the bar 67. Specification 320,704, [Class 106 (ii), Dynamometers &c.], is referred to.

Each pair of rib sections are also connected by a link 25 and each plate is connected by a stretcher 30 to a crown piece 7, which is secured to the stick section 1 by a button washer 9 and screw 11, and by a stretcher 31 to a grooved flange 37 on the stick section 2. In order to close the umbrella, the stick section 1 is pushed into the section 2 until a nut 50 in the lower end of the section 1 engages a threaded rod 51 connected to a cap 49, whereupon rotation of the cap completely telescopes the sections' 1, 2 causing the rib sections 17 and stretchers 30, 31 to fold against the stick and the plates 21 to turn about their pivots 20 associated, with the sections 17. The links 25 thereupon constrain the ribsections 19 to fold upwardly against the sections 17, Fig. 6 showing a transition stage. In order to open the umbrella, it is only necessary to rotate the cap until the rod 51 is disengaged from the nut 50, whereupon a spring 40 completes the outward movement of the stick section 1. The piece 7 is formed with radial arms provided with dependent bearings 16 and apertured recesses 34 to accommodate the pivot pins of the rib sections 17 and the stretchers 30.
